I have class A and B.  A has many Bs.
B has a field is_visible which can be true or false
I have alot of As as well

I can acquire a set of As by doing the follwoing:

@As = X.find_by...

Need to iterate over all the As, and return Bs where B.is_visble is true.

Best way to do this?

I've been away from Ruby for way too long!

I think you'll need to put "X" into an array, you can then iterate through the array with array.each, where you can then do something like this:

As.each do
...do stuff...
end
